Mn-containing (2 and 4 mass%) Al–Mn-based alloys were fabricated by high-speed twin-roll casting (HSTRC). Al–4 mass%Mn–1 mass%Si strips contained coarse particles in the central band of cast strips. Microstructure chemical analyses revealed that primarily Al6(MnFe) β-Al(MnFe)Si. These formed during solidification process residual liquid, which slowly cooled after strip exited roll gap HSTRC. Ho...

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited arrhythmogenic disease characterized by the development of adrenergically mediated bidirectional and polymorphic ventricular tachycardia in individuals with a normal heart.1 Although this disease was initially described by Coumel2 in the seventies, it was only after the identification of its genetic substrate that inte...

In 2007, we marked the 40th anniversary of the birth of invasive clinical electrophysiology. Of course, before 1967, cardiac arrhythmias were documented electrocardiographically, and their possible mechanisms were analyzed ingeniously and explained beautifully by giants such as Katz and Pick,1 Scherf and Schott,2 and Bellet.3 In the 1940s and 1950s, Hecht,4 Latour and Puech,5 and Giraud et al6 ...

The phase composition and structure of as-cast deformed Al-1.53Cu-1.66Mn-0.38Zr-0.15Cr-0.15Fe (wt.%) were investigated. radial shear rolling was used for the deformation alloy. alloy consists aluminum solid solution, eutectic Al6(FeMn) Al2Cu, as well Al7Cr Al20Cu2Mn3 dispersive particles. It is assumed that results in refinement partial dissolution dispersoids. Along with this, significant grai...

To ascertain the effect of solution pH Na2MoO4 chemical conversion treatment for aluminum/steel joints on corrosion resistance, AA5083 aluminum alloy and AISI 1045 carbon steel were immersed in 50 mM at ranges 8–12 under galvanically coupled condition. Subsequently, diluted synthetic seawater, galvanic resistance connected to was assessed. The number localized damages counted, treated 11 found ...
